AUGUST O. DOBRIOK, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE IMPERIAL BRASS-MANUFAGTURING; COMPANY, OF- CHICAGO, ILLINOIS, A CORPORATION OF ILLI-NOIS.

To all whom it may concern:

Be it known that I, AUGUST 0. Dofinrcn, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certaln new and useful Improvements in Valve-ItegulatmgMeans, of which the following is a" full,

clear, and exact specification.

Figure 1 is a side elevation of my invention shown as applied to thedashboard of an automobile;

Fig. 2 is a central longitudinal section of,

the same on a larger scale;'and

Figs. 3 and 4 are, transverse sections on the lines 33 and 14,respectively, of Fig. 2.

In carrying out my invention, I preferably employ an externally threadedgulde cylinder 10, in which is mounted to slide an adjusting rod 11,which will preferably be. provided with a finger piece 12 securedthereto.

Thecylinder is passed through a suitable;

aperture in the dashboard 13 of an automobile, and is secured in placeby the cap 14 screwed onto one end ofthe cylinder and resting againstthe front of the dashboard 13, while the set nut 15 and lock nut 15 onthe other side of the dashboard are screwed up, as shown in Fig. 1, tosecure theparts securely in place. The adjusting rod 11 has secured totheinner end thereof the wire 16, which extends to and is secured to thethrottle valve of the .carbureter in the customary manner, it beingguided and pros tected by the tube 17 preferably formed of spirallywound wire. This tube is secured.

in place by the nut 18 through which it passes and which is threaded onthe other end of the cylinder 10 from the outer end on which the cap 14is screwed.- The end of a wire 16 is conveniently looped throughSpecification of Letters Patent.

Application (filed May as, 1919-. Serial No. 300,372.

the aperture 19 formed in the reduced end of the adjusting rod 11.

To secure yieldingly the adjusting rod 11 v in any desired position inthe cylinder 10, I

form on the rod a' number of shallow annular grooves 20 corresponding tothe number of positions to which it ,is desired to adjust the valve, andcooperating with said grooves is a small helically coiled spring 21,consisting of two or more spires, and suitably confined in an annularrecess 22 formed in the cap 14 at the end thereof so that the spring 21is confined between the end of the cylinder 10 and the bottom of thegroove 22 in such a manner that the spring can not move except to expandsufliciently to allow the rod 11 to pass from, one position ofadjustment tothe other, the springcontracting after it passes each ridgebetween the adjacent grooves 20 so as to yieldingly hold the rod in anyposition of-adjustment in a manner that will be readily apparent.

Another feature of myinvention is the novel combination by which theflexible tube 17 is secured to the cylinder 10, and to this end I taperoff its end 23,. and insaid tapered end I out two or more slides 24, andform in the outer end of the nut 18a correspondingly tapered portion 25.As the external diameter of the tube 11 is substantially .equal'to theinternal diameter of the cylinder 10, it will be obvious that .when' theparts are assembled, asseen at the lefthand end of Fig. 2, and the nut18 is tightened up, the reduced end of the cylinder 10 will becontracted and will grip the tube 17 very tightly, and hold it as'firmlyas if it were soldered, while leaving it in conditionso that it can bereadily disconnectedif the wire 16 is broken or it is dewhich I atpresent consider best adapted to carry out its purposes, it is capableof some modification, and I donot desire to be limited in theinterpretation of the. following claims, except as maybe necessitated bythe state of the prior art. 1 1

What I claim as new and desire to secure by Letters Patent of the UnitedStates is:

1. In an apparatus of the class described, the combination with a guidecylinder adapted to be secured' in the dashboard of an automobile, of anadjusting rod sliding therein and provided with annular grooves thereon,a short coiled spring surrounding said rod and adapted to cooperate sin1y 5 with any of saidgrooves, and means or confining: the spring toprevent its movement with the rod while permitting expansion to allowthe rod to be adjusted to and heldin any of its positions of adjustnient2. In an apparatus, of the class described, the combination with a guidecylinder adapted to be secured in the dashboard of an automobile, of anadjusting rod sliding therein and provided with'annular grooves thereon,a short coiled spring surrounding said rod and adapted to cooperatesingly with, any of said grooves, and a cap screwed on one end ofthecylinder and having an annular recess therein adjacent said end ofthe roper dimensions to receive and confine the s ring in the manner andfor the purpose set orth, p

. In an apparatus of the class described, the combination with anexternally threaded guide cylinder, of an adjusting i-od sliding thereinand provided with annular'grooves thereon, a short coiledspring'surrounding said rod and adapted to cooperate singly anautomobile and having its rear end externally threaded and provided witha taadapted to be secured in the dashboard of pered, split portion, ofan adjusting rod I sliding therein, means for holding the rod in anydesired position of adjustment, a wire attached to the endof the rod, "aflexible tube adapted to fit in the end of the cylinder, and a nutthreaded on the rear end of the cylinder and having a reduced internallytapered portion cooperat ing with thetapered and split endv of thecylinder for the purpose described.

In' witness whereof I have hereunto set my hand and affixed my seal this20th day of May, A. D. 1919.
